Funny that you linked that specific video. That video and the concept of the Wall of Awful is something I use a lot when trying to explain my situation to others.
It sounds like motivating yourself to do something you have to do is hard (work), while something you want to do is easy (animal crossing).
It might be helpful to take some time to just sit and reflect on why you’re having trouble starting work. Write down the things that you’re worried about. The bricks in your wall of awful. Write down what you liked about animal crossing, why you spent so much time on it. And notice the differences between both. Is it interest? Challenge? Freedom? External pressure?
